Java Java Objects Creating the MVP Scrabble Tiles

Bummer! While you could definitely solve this using an if statement, try returning the result of the expression.

I dont understand where i am wrong i tried returning the variable but it is still showing me an error please help

ScrabblePlayer.java
public class ScrabblePlayer {
  // A String representing all of the tiles that this player has
  private String tiles;
  private String correctTile;
  private String falseTile;

  public ScrabblePlayer() {
    tiles = "";
    correctTile = "";
    falseTile = "";
  }

  public String getTiles() {
    return tiles;
  }

  public void addTile(char tile) {
    // TODO: Add the tile to tiles
    tiles += tile;

  }

  public boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
    boolean isCorrectTile = tiles.indexOf(tile) != -1;
    if(isCorrectTile){
      correctTile += tile;
    }else{
      falseTile += tile;
    }
    return tiles.indexOf(tile) != -1;
  }

}

You almost have it there. You do not need to use an if statement. You only need the following returned: tiles.indexOf(tile) != -1; This statement is either true or false. Returns true if the index of the character is >= 0 and returns false if the index of the character is -1 (which we know -1 means that the string tiles does not contain the tile). This is how the method indexOf works. https://docs.oracle.com/javase/8/docs/api/java/lang/String.html#indexOf-int-

  public boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
    return tiles.indexOf(tile) != -1;
  }
